I strongly suggest (depending on your budget), that you get a Filco keyboard from ArmyGroup. Don't get intimidated by the lack of English, just use Google Chrome to translate or follow step by step instructions in the ArmyGroup thread to order it.
I live in Canada, BC. I bought a Filco Tenkeyless Brown from for $159 on the dot. Once it arrived, I got no taxes. I wasn't just lucky either, many report they don't get customs/taxes/duties from ArmyGroup. I asked them to mark it as a gift just in case as well.
I also just ordered the Filco wrist rest from them (if you want this, buy it with your keyboard to save on the shipping charge!), and again no customs/duties/taxes.
I had a DAS Professional S, and much more prefer the Filco.
